FS#223 - op_power.sh kills gles context

Tags:

opengles and op_power.sh don't like each other very much.
whenever returning from low power to full power mode again, opengles rendering is just dead.
the reason for this issue are following 2 lines within op_power.sh
18 echo 0 > /sys/devices/platform/omapfb/graphics/fb0/blank
...
66 echo 1 > /sys/devices/platform/omapfb/graphics/fb0/blank
if these lines are removed/commented, the gles rendering just resumes fine.
